I upgraded my hardware and moved my PMS settings over to a new machine with Windows 10 and I'm having the same issue as many others, not being able to play media back locally at a higher rate than 3mb without a jittery stutter (on the web app on a local machine - and on the Plex App from a Samsung phone some movies just buffer for 30+ seconds and then error out). I'm also having the same issue playing video directly on the computer hosting my PMS files (web app), heavy jittering and stuttering unless I bump the quality down to 3mb. Haven't thoroughly tested my Plex app on my other local devices yet but buffering up to play a video seems lengthy at times. This is all on a local hardwired gigabit network and my PMS is on a box with a 6800k processor and 32GB of RAM. Haven't tried a connection from outside of my house yet. Everything worked fine on my Windows 7 install on an older server.
Am I understanding properly that a proper uninstall and fresh from scratch install of the server including re-adding my media back into the fresh install might be the best path to a solution?
I can pull and send log files but, it looks like this is a common issue through many forum thready.
Thanks for any suggestions.
